Ear
The Organ of Hearing
and Balance
Sound waves enter the ear
through the auditory canal and
then travel through the ear
drum, where they are
converted to vibrations.
Millions of tiny hairs in the
inner ear’s cochlea convert the
vibrations into electrical nerve
signals, which are sent to the
brain through the Eustachian
tube for processing.
